IB time and sales shows it as 6 x 100, although IHUB does show it as 6. I don't believe that an odd lot below 100 shares impacts the last trade price nor does it show up on level 2 bid/ask. At least that's how it was years ago. A trade of a single share to paint the tape at the close did not work. One had to trade at least 100 shares. Maybe it's different now.
